Negative-noting an image in which the brightness values of the subject are reproduced so that the lightest areas are shown as the darkest.
(Google result) Negative-a negative may refer to three different things, although they are all related.
My explination for why the positive and negative are what they are is known as ''color reversed''. For the negative, the black areas are in the sky and the white is on my ground. And for the positive, objects on the ground are black and the sky is white, which is the correct look alikes. So I think the negative's colors are upside down and the positive's are right side up. *Note- It's like someone in the universe took earth, put it in the wash machine, washed it, and with it tumbleing in many derections, the colors got mixed up. Making the colors in the wrong areas back down on earth! But I'm very interested in the negitive/positive therory!
